If we divide 1228 by 161, we get 7 and a remainder of 101.
The next digit of our result is 7. 
Result so far: 3717.0
Deduct 1127 from 1228 and we're left with 101.
Take the next digit (5) from the dividend and append it to 101, then repeat: 1015 / 161

Moving on to step 7:
161 goes into 1015 6 times with a remainder of 49.
The next digit of our result is 6. 
Result so far: 37176.0
If we take 966 away from 1015, we end up with 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 161

Advancing to step 8:
495 divided by 161 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 371763.0
Subtracting 483 from 495 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 161 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 371763.0
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
If we divide 1200 by 161, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 371763.07
Deduct 1127 from 1200 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 11:
730 divided by 161 is 4 with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 371763.074
Subtracting 644 from 730 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 12:
When dividing 860 by 161, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 371763.0745
Subtracting 805 from 860 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 13:
When dividing 550 by 161, we get 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 371763.07453
If we subtract 483 from 550, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 14:
161 can be fit into 670 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 371763.074534
Deduct 644 from 670 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 15:
161 can be fit into 260 1 times, resulting in a remainder of 99.
Record the quotient 1 as the next digit in the result. 
Result so far: 371763.0745341
Subtracting 161 from 260 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 16:
990 divided by 161 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 371763.07453416
Subtracting 966 from 990 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 371763.07453416, and the remainder is 2.4e-08.
